## Discrepancy

DURING PRE-FLIGHT INSPECTION, FLIGHT CREW REPORTED A NOISE FROM THE RUDDER.  INSPECTION OF THE RUDDER SYSTEM REVEALED A FAILED BEARING IN THE BEARING SUPPORT OF THE LOWER RUDDER HINGE.  THE OUTER CASE OF THE BEARING HAD TWO PIECES BROKEN OFF AND MISSING.  BEARING WAS RETURNED TO MANUFACTURER FOR INVESTIGATION.  RECOMMEND REPLACEMENT OF BEARINGS WITH BETTER QUALITY BEARINGS.
